Isolation on Chocolate Agar Culture of Legionella pneumophila Isolates from Subcutaneous Abscesses in an Immunocompromised Patient.

Cutaneous infections due to Legionella species have rarely been reported (L. J. Padrnos, J. E. Blair, S. Kusne, D. J. DiCaudo, and J. R. Mikhael, Transpl Infect Dis 16:307-314, 2014; P. W. Lowry, R. J. Blankenship, W. Gridley, N. J. Troup, and L. S. Tompkins, N Engl J Med 324:109-113, 1991; M. K. Waldor, B. Wilson, and M. Swartz, Clin Infect Dis 16:51-53, 1993). Here we report the identification of Legionella pneumophila isolates, from subcutaneous abscesses in an immunocompromised patient, that grew in an unusual medium for Legionella bacteria.
